Reviewing the files from your upgrade attempt, you have installed
packages from the deadsnakes PPA. Some of the packages installed are
newer than those in the official archive, which is keeping some python
packages installed which then prevents the upgrade from being
calculated. Please try using the official versions of python3 from the
Ubuntu archive. After that you can try upgrading again and if it still
fails open a new bug report. Thanks and good luck!
